ruby on rails - Rendering string with erb content on page -


i found many posts problem, it's seems none of them solves problem. got code want render string:

<%= button_to "/admin/#{contr_name}/#{obj.id}", method: :delete, class: 'btn btn-danger btn-resource-destroy', data: {toggle: 'tooltip'}, title: 'delete' %>    <%= icon('trash-o') %> <span class='sr-only'>delete</span> <% end %>

i have tried this:

template += "<div class='col-sm-4'>" template += "<%= button_to \"/admin/#{contr_name}/#{obj.id}\", method: :delete, class: 'btn btn-danger btn-resource-destroy', data: {toggle: 'tooltip'}, title: 'delete' %>    <%= icon('trash-o') %> <span class='sr-only'>delete</span> <% end %>" template += "</div>" erb.new(template).result(binding)

but syntax errors.

how can fix this?

i suggest use partials instead.

first, define partial at, example, views/shared/_delete_button.html.erb:

<%= button_to "/admin/#{contr_name}/#{obj.id}", method: :delete, class: 'btn btn-danger btn-resource-destroy', data: {toggle: 'tooltip'}, title: 'delete' %>    <%= icon('trash-o') %> <span class='sr-only'>delete</span> <% end %>

then, can render partial wanted parameters:

render 'shared/delete_button', contr_name: [contr_name], obj: [obj]

replacing [contr_name] , [obj] whatever want variables assigned to.

or, better, allow partial extract controller's name predefined variables, this:

<%= button_to "/admin/#{controller.controller_name}/#{obj.id}", method: :delete, class: 'btn btn-danger btn-resource-destroy', data: {toggle: 'tooltip'}, title: 'delete' %>    <%= icon('trash-o') %> <span class='sr-only'>delete</span>  <% end %>

now need supply obj when rendering it.

render 'shared/delete_button', obj: [obj]

you use named routes, , [route_name]_path(obj) instead of manually constructing path.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
